A safe traction trolley

Abstract

Provided is a safe traction device. A plurality of moving rollers are mounted under a moving device, one end of the traction device is provided with a tension input fixing rod, a safety traction space is arranged inside the traction device, a venting hole is formed in the upper portion of the traction device, a safety material inlet port is formed in the upper portion of one end, away frame the tension input fixing rod, of the traction device, and a tension hedging mechanism is disposed inside the safety traction space, a tension transmission connection rod is connected to one end surface ofthe tension hedging mechanism, a tension output rod is arranged on one end surface, located in outer space, of the tension transmission connection rod, and a fail-safe device is arranged on the lowerportion of one end, away from a tension input fixing rod, of the traction device. The traction device can connect a traction object with a towed object, can reduce the impulsive force generated by thetwo objects during the traction, so that the output of the traction force is more gentle, damage of the towed object caused by the overlarge impulsive force is avoided, and simultaneously the fail-safe device avoids the result that the towed object is damaged due to excessive traction.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a safe traction trolley. Background technique [0002] At present, in large-scale engineering projects such as bridge repairs, road repairs, and building constructions, there are more and more harsh working environments. During use, engineering equipment will inevitably encounter the dilemma of being stuck in the mud and cannot get out. At this time, a tractor is needed. Pull out the equipment. As we all know, the more advanced the equipment, the more precise the components and the higher the precision requirements. Such a little damage may cause the overall equipment to be unusable. However, the existing situation is still towed by ropes. The pulling speed and The size of the force depends entirely on experience. There are too many uncertain factors in this kind of behavior, and the outcome of the matter is completely out of control. Contents of the invention [0003] The pur...

[0002] At present, in large-scale engineering projects such as bridge repairs, road repairs, and building constructions, there are more and more harsh working environments. During use, engineering equipment will inevitably encounter the dilemma of being stuck in the mud and cannot get out. At this time, a tractor is needed. Pull out the equipment. As we all know, the more advanced the equipment, the more precise the components and the higher the precision requirements. Such a little damage may cause the overall equipment to be unusable. However, the existing situation is still towed by ropes. The pulling speed and The size of the force depends entirely on experience. There are too many uncertain factors in this kind of behavior, and the outcome of things is completely out of control.
